Description

Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a key and a smart lock. Background Art

[0002] For convenience, more and more people are choosing smart locks as door locks. These locks can be unlocked using facial recognition, fingerprint recognition, passwords, and mobile phones, eliminating the need for keys. To prevent malfunctions and prevent unlocking, smart locks often include mechanical keys. A keyhole is provided on the panel, and the corresponding mechanical key is inserted into the keyhole to unlock the lock.

[0003] To enhance the aesthetics of the front panel and provide a degree of theft resistance, some smart locks feature an inner panel and an outer panel connected to the inner panel. A slot is provided between the inner and outer panels, and a keyhole is opened on the side wall of the slot toward the lock cylinder. To further enhance theft resistance, the keyhole includes a transition hole and a lock hole, which are arranged in sequence. A mechanical key must pass through the transition hole to be inserted into the lock hole, making it more difficult for a thief to insert a tool into the keyhole itself.

[0004] However, because a mechanical key requires axial force along the keyhole when inserted, the slot width must be at least as wide as the key length to ensure it fits properly. This ensures the key remains parallel to the keyhole and can be translated into alignment. The presence of the transition hole increases the length of the key and also increases the slot width by the length of the transition hole. This reduces the ease with which lock-picking tools can penetrate the keyhole, resulting in poor security. Utility Model Content

[0005] In view of this, the present application provides a key to solve or improve the problem that the slot where the keyhole is located requires a larger width, resulting in poor anti-theft performance.

[0006] In a first aspect, the present application provides a key comprising an extension section and an unlocking section connected to one end of the extension section, wherein the unlocking section is adapted to be inserted into a keyhole to unlock the key, the extension section comprising a plurality of blocks abutting each other end to end, and two adjacent blocks being connected by an elastic member, wherein:

[0007] When two adjacent blocks are relatively displaced, the elastic member is suitable for driving the two adjacent blocks to reset.

[0008] Optionally, the elastic member is an elastic rope, and a through hole is provided on the block. The elastic rope passes through the through holes on two adjacent blocks in sequence and is tightened to tighten the two adjacent blocks to be parallel and against each other.

[0009] Optionally, the elastic rope passes through the through holes on all the blocks in sequence and is tightened to tighten the ends of the blocks to be parallel and against each other in sequence.

[0010] Optionally, at least two through-holes are provided on the block, and the elastic rope is passed through each through-hole.

[0011] Optionally, the number of the through holes provided on the blocks is an even number, and the elastic rope passes through the through holes on the blocks in sequence and then is connected end to end and tightened.

[0012] Optionally, both ends of the block are provided with a plug connector and a plug hole respectively, and the plug connector on one block can be plugged into the plug hole on the other block.

[0013] In a second aspect, the present application also provides a smart lock, comprising: any of the keys described above.

[0014] Optionally, the lock body comprises an outer panel, an inner panel, a rotating body, a guide cylinder and a lock core, the rotating body is rotatably connected to a rotating hole opened on the inner panel, and both ends of the guide cylinder are respectively connected to the inner panel and the lock core;

[0015] The rotating body is provided with a groove, and a through hole communicating with the guide cylinder is provided through the bottom wall of the groove, so that the key can sequentially pass through the through hole and the guide cylinder and be inserted into the lock hole on the lock core;

[0016] The outer panel is connected to the inner panel. The outer panel is located in the extending direction of the through hole and a slot for a key to be inserted is formed between the outer panel and the inner panel.

[0017] Optionally, a snap-in hole is provided on the side wall of the block, a spring piece is connected to the rotating body, the first end of the spring piece is connected to the rotating body, and the second end of the spring piece extends into the extension space of the through hole. When the key passes through the through hole, the second end of the spring piece can be inserted into the snap-in hole on one of the block.

[0018] Optionally, the side wall of the groove is an inclined surface, and the inclined surface is inclined from outside to inside in the direction toward the guide cylinder.

[0019] The present application provides a key comprising an extension section and an unlocking section. The unlocking section is configured as a key for inserting into a keyhole to unlock the key, and the teeth on the key correspond to the keyhole. The extension section comprises a plurality of blocks, each of which is sequentially connected end to end to form an extension section, and the unlocking section is fixedly connected to the block at the very end. The two blocks are connected by an elastic member, and under the elastic force of the elastic member, the two adjacent blocks are pulled closer to each other and tightened, so that every two adjacent blocks abut against each other. In this way, the blocks abut against each other in turn to form a straight extension section, and the blocks are parallel to each other. Force can be applied to any one of the blocks to cause relative displacement relative to an adjacent block. When the two adjacent blocks are relatively displaced, the elastic force of the elastic member is overcome and the elastic member is stretched. After the force is released, the elastic member rebounds to reset the two blocks.

[0020] In this way, the key can be tilted by gripping the extension and inserting it into the slot between the outer and inner panels until the unlocking section enters the transition hole. Applying force to push the extension causes the extension to bend for the first time between two adjacent blocks, so that the portion of the extension near the unlocking section at the first bend is parallel to the transition hole. At this point, force can be applied to insert the portion of the extension near the unlocking section at the first bend into the transition hole. Continue applying force to push the extension, causing the remaining extension to bend for a second time between two adjacent blocks, so that the portion of the extension near the unlocking section at the second bend is parallel to the transition hole. At this point, force can be applied to insert the portion of the extension near the unlocking section at the second bend into the transition hole. Similarly, after multiple bends, the extension can be gradually inserted into the transition hole, allowing the unlocking section to enter the keyhole. At this point, rotating the extension rotates the unlocking section to unlock the key. Therefore, regardless of the length of the keyhole formed by the transition hole and keyhole, the slot width only needs to ensure that the unlocking section of the key can enter the transition hole and the unlocking section can be inserted into the keyhole to unlock the key. There is no need to increase the slot width by the transition section. The width requirement of the slot is reduced, thereby increasing the difficulty of the lock-stealing tool to enter and improving the anti-theft performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0034] The following combination Figures 1 to 9 , describing the embodiments of the present application.

[0035] According to an embodiment of the present application, on the one hand, a key is provided, such as Figure 1 and Figure 2 As shown, the lock comprises an extension section and an unlocking section 1. The unlocking section 1 is configured to be inserted into a key to unlock the keyhole, with the teeth on the key corresponding to the keyhole. The unlocking section 1 is inserted along the transition hole of the keyhole, and after passing through the transition hole, further force is applied to insert it into the keyhole, thereby unlocking the lock body.

[0036] The extension section includes a plurality of blocks 2, and the blocks 2 are sequentially connected end to end to form the extension section, and the unlocking section 1 is fixedly connected to the block 2 at the tail end.

[0037] For two adjacent blocks 2, the abutting surfaces of the two adjacent blocks 2 are both flat. The two blocks 2 are connected by an elastic member 3. Under the elastic force of the elastic member 3, the two adjacent blocks 2 are pulled closer together and tightened, so that each two adjacent blocks 2 abut. In this way, the blocks 2 abut in sequence to form a straight extension, and the blocks 2 are parallel to each other.

[0038] At this time, force can be applied to any block 2 to cause it to move relative to the adjacent block 2. When the two adjacent blocks 2 move relative to each other, the elastic force of the elastic member 3 is overcome and the elastic member 3 is stretched. After the force is removed, the elastic member 3 rebounds and the two blocks 2 return to their original position, that is, the two blocks 2 return to being parallel and abutting each other end to end.

[0039] That is, force can be applied at any position to overcome the elastic force of the elastic member 3 and bend the extension section. After the force is removed, the elastic member 3 rebounds and the extension section returns to being straight.

[0040] Set it up like this, Figure 8 As shown, the key can be tilted by gripping the extension and inserting it into the slot 14 between the outer panel 7 and the inner panel 8 until the unlocking section 1 is inserted into the transition hole. At this point, applying force to push the extension can cause the extension to bend for the first time between two adjacent blocks 2, so that the extension near the unlocking section 1 at the first bend is parallel to the transition hole. At this point, force can be applied to insert the extension near the unlocking section 1 at the first bend into the transition hole.

[0041] Then continue to apply force to push the extension section so that the remaining extension section bends for the second time at a position between two adjacent blocks 2, so that the part of the second bend close to the unlocking section 1 is parallel to the transition hole. At this time, force can be applied to insert the part of the second bend close to the unlocking section 1 into the transition hole.

[0042] Similarly, after multiple bends, the extension section can be gradually inserted into the transition hole so that the unlocking section 1 is inserted into the lock hole. At this time, rotating the extension section can rotate the unlocking section 1 to complete the unlocking.

[0043] With this arrangement, regardless of the length of the keyhole formed by the transition hole and the lock hole, the width of the slot 14 only needs to ensure that the unlocking section 1 of the key can enter the transition hole and insert into the lock hole to unlock the key. This eliminates the need to increase the width of the slot 14 by the value of the transition section. This reduces the required width of the slot 14, making it more difficult for tools used to steal the key to penetrate, and thus improving theft prevention.

[0044] In an optional embodiment, if Figure 2As shown, the elastic member 3 is configured as an elastic cord. Each block 2 is provided with a perforation 4. The elastic cord is passed through the perforations 4 of two adjacent blocks 2 and tightened. Under the elastic action of the elastic cord, the adjacent blocks 2 are brought closer together and tightened, so that each pair of adjacent blocks 2 abuts. In this way, the blocks 2 abut one another to form a straight extension, each block 2 being parallel to one another. The connection between any two adjacent blocks 2 can be bent, thereby applying force at a specified location to overcome the elastic force of the elastic cord and bend the extension. When the force is removed, the elastic member 3 rebounds, restoring the extension to its straightness.

[0045] For tightening the elastic cord, the first end of the elastic cord can be passed through the perforation 4 on the first block 2 and then tied. The second end of the elastic cord is passed through the perforation 4 on the second block 2 and then tied after tightening the elastic cord.

[0046] In a further embodiment, an elastic cord may be passed through the through-holes 4 of each block 2 in sequence, then tightened and knotted at both ends. Thus, under the elastic action of the elastic cord, the blocks 2 are tightened end to end, and the blocks 2 are parallel to form a straight extension.

[0047] Furthermore, two through-holes 4 are provided on the block 2, arranged parallel to each other and extending along the extension direction of the extension section. An elastic cord is passed through each through-hole 4 and tightened. The elastic cords in both through-holes 4 simultaneously tighten the two adjacent blocks 2, making the connection more reliable and secure.

[0048] The two perforations 4 can be respectively arranged on both sides, so that the elastic force is more uniform.

[0049] It is worth noting that the number of the through holes 4 can be set to be greater than two to further increase the connection reliability.

[0050] In a further embodiment, the number of through-holes 4 provided on the blocks 2 is an even number. The first end of the elastic cord is passed through the first through-hole 4 on each block 2 from the beginning to the end, and then passed through the second through-hole 4 on each block 2 from the end to the beginning. Similarly, the second end of the elastic cord is passed through each through-hole 13 on each block 2 in sequence.

[0051] Since the number of the perforations 4 is even, the second end and the first end of the elastic cord are located on the same side, and after the elastic cord is tightened, the first end and the second end are tied together to secure them. Thus, the elastic cord is used to tighten the blocks 2 to offset each other in sequence.

[0052] like Figure 2As shown, two through-holes 4 are provided. The first end of the elastic cord is passed through the first through-hole 4 of each block 2, from the beginning to the end, and then through the second through-hole 4 of each block 2, from the end to the beginning. At this point, the second and first ends of the elastic cord are both located on the head side. After tightening the elastic cord, the first and second ends are tied together to secure the elastic cord. This allows the elastic cord to tighten each block 2, causing it to counteract each other.

[0053] As an optional embodiment, Figure 3 As shown, plug holes 6 and plug connectors 5 are provided at the head and tail ends of the blocks 2, respectively. A through-hole 4 extends from the bottom of the plug hole 6 to the rear end of the plug connector 5. When two adjacent blocks 2 abut against each other, the plug connector 5 on one block 2 fits into the plug hole 6 on the other block 2. This ensures a more stable abutment between the two adjacent blocks 2 and prevents relative displacement between the two blocks 2.

[0054] For the block 2 on the front side, the plug hole 6 of the block 2 can be used to accommodate the elastic rope to reduce the space occupied. For the block 2 on the rear side, the unlocking end is fixedly connected to the plug connector 5 of the block 2.

[0055] According to an embodiment of the present application, another aspect is provided, comprising: a lock body and any of the above keys. The technical effects of the smart lock are consistent with those of the key, so they will not be described in detail.

[0056] In an optional embodiment, if Figure 4 As shown, the lock body includes an outer panel 7, an inner panel 8, a rotating body 9, a guide cylinder 10, and a lock core 11. A rotary hole is provided on the inner panel 8, and the rotating body 9 is rotatably connected to the rotary hole so that the rotating body 9 can rotate around the axis of the rotary hole. A groove 12 is provided on the rotating body 9, and a through hole 13 is provided on the bottom wall of the groove 12 so that the through hole 13 passes through the rotating body 9. The first end of the guide cylinder 10 is connected to the inner panel 8 so that the through hole 13 is aligned with the guide cylinder 10. The second end of the guide cylinder 10 is connected to the lock core 11 so that the through hole 13, the guide cylinder 10, and the lock hole on the lock core 11 are aligned. At this time, the through hole 13 and the inner hole of the guide cylinder 10 form a transition hole, and the key can pass through the through hole 13 and the guide cylinder 10 in sequence and then be inserted into the lock hole on the lock core 11.

[0057] The outer panel 7 is connected to the inner panel 8, and a slot 14 for a key to be inserted is formed between the outer panel 7 and the inner panel 8. The outer panel 7 is located in the extending direction of the through hole 13 to prevent a common key from being directly inserted into the through hole 13 along the extending direction of the through hole 13.

[0058] In this way, the extended grip section can be used to tilt the key into the slot 14 between the outer panel 7 and the inner panel 8 until the unlocking section 1 is inserted into the groove 12 and then into the through hole 13 .

[0059] After that, force is applied to push the extension section, which can cause the extension section to bend for the first time at a position between two adjacent blocks 2, so that the extension section near the unlocking section 1 at the first bending point is parallel to the through hole 13. At this time, force can be applied to push the extension section near the unlocking section 1 at the first bending point through the through hole 13 and insert it into the guide cylinder 10.

[0060] Then continue to apply force to push the extension section so that the remaining extension section bends for the second time at a position between two adjacent blocks 2, so that the part of the second bend close to the unlocking section 1 is parallel to the through hole 13. At this time, force can be applied to push the part of the second bend close to the unlocking section 1 through the through hole 13 and insert it into the guide cylinder 10.

[0061] Similarly, after multiple bends, the extension section can be gradually passed through the guide cylinder 10, so that the unlocking section 1 is inserted into the lock hole. At this time, rotating the extension section can rotate the unlocking section 1 to complete the unlocking. When the extension section rotates, the rotating body 9 rotates with it.

[0062] In some embodiments, such as Figure 9 As shown, a groove 15 is provided on the side wall of the guide cylinder 10 to facilitate air circulation and reduce resistance caused by the air while ensuring strength.

[0063] In an optional embodiment, if Figures 5 to 7 As shown, a snap-in hole 17 is provided on the side wall of the block 2, and a spring clip 16 is disposed within the groove 12 on the rotating body 9. The first end of the spring clip 16 is connected to the side wall of the groove 12, and the second end of the spring clip 16 extends into the through hole 13. When the key passes through the through hole 13, the second end of the spring clip 16 can extend into the snap-in hole 17 on the block 2. When force is applied to insert the key toward the keyhole, the spring clip 16 deforms and leaves the snap-in hole 17 on the block 2. As the key continues to be inserted, the spring clip 16 aligns with the snap-in hole 17 on the next adjacent block 2, causing the spring clip 16 to rebound and insert into the snap-in hole 17.

[0064] Similarly, when the key is pulled out with force back toward the lock hole, the spring piece 16 is deformed and leaves the engaging hole 17 on the block 2. As the key continues to be pulled out, the spring piece 16 aligns with the engaging hole 17 on the next adjacent block 2, so that the spring piece 16 rebounds and is inserted into the engaging hole 17.

[0065] This arrangement produces a sense of frustration and plays a certain clamping role, making it easier to apply force to the extended end of the key to deform it.

[0066] It is worth noting that when the unlocking section 1 of the key is fully inserted into the lock hole, the second end of the elastic piece 16 is just inserted into the engaging hole 17 on one of the blocks 2 .

[0067] In an optional embodiment, the side wall of the groove 12 is set as a slope, wherein the slope is inclined from outside to inside in the direction toward the guide cylinder 10, that is, the outer edge of the slope is connected to the top side of the groove 12, and the inner side of the slope is connected to the side of the through hole 13.

[0068] In this way, after the unlocking section 1 of the key is inserted into the groove 12 and rests on the inclined surface, force is continued to be applied so that the unlocking section 1 slides along the inclined surface to the through hole 13 and is inserted into the through hole 13. This guides the insertion of the key and makes the operation more convenient.

[0069] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the present application.
